HORSE-DETACHER.

SPECIFICATION formingpart of Letters Patent No. 261,079, dated July 11, 1882.

Application filed March 2, 1882. (Model) To all whom it may concern:

Be it known that I, JOHN H. GLOW, a citizen of the United States, and a resident of Sheridan, in the county of Yam Hill and State of Oregon, have invented a new and valuable Improvement in Horse-Detachers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure] of the drawings is a representation of a plan view of a wagon-tongue, showing my 5 improvement. Fig. 2 is a detail perspective view of part of a single-tree. Fig. 3 is a side view of the end of the tongue, showing the neck-yoke attachment; and Fig. 4 is a sectional view.

This invention has relation to safety attachments for thedraft of vehicles; and it consists in the construction and novel arrangement in connection with a pivoted rod extending from one end to the other of a single-tree or neck yoke, and carrying books or fastening devices at its ends, of an angle-lever rigidly secured to the middle portion of said rod, an operatingstrap connected permanently with one end of said lever and partially to the other end there- 0 of, and a spring-keeper bearing against said lever, all as hereinafter set forth and particularly pointed out in the claim appended.

In the accompanying drawings, the letter A designates the pole of a vehicle; B, the double- 5 tree; 0, the single tree, and D the neckyoke. Each single-tree is provided with a rod, e, extending along its front edge, and connected to the single-tree by means of staples g and drafteyes h, the latter forming portions 0 of the bands It. at the ends of the single-tree. The rod 6 is pivoted in these hearings so that it can be turned axially by means of a short lever, Z, which is rigidly fastened to its middle portion. The ends of the rod 0 are bent to 5 form the hooks m, to which the traces are connected, the direction of these hooks being parallel or nearly so to the arm 8 of the lever l, to which the operating-strap t is permanently connected. The lever l is angular in form,

being connected by its middle portion or arm,

n, to the rod and by its arm 8 to the strap t. This strap extends along the lever toits other end, a, which is provided with holdingwings or semi-clasps n, to engage the strap and hold it temporarily in connection with this arm 2 of the lever, said arm a being turned in the opposite direction to the arm 8, as indicated in the drawings. A spring, w, is secured to the single-tree and bears against the lower arm, 8, serving to keep it turned to the rear in position to hold the end hooks of the rod e in engagement with the traces. Should any accidentoccur on the road rendering it advisable to disconnect the traces, the strap tis designed to be pulled by the occupant of the vehicle. This will draw the arm 2 of the lever upward, disconnecting the lever from the spring-keeper, and then the strap t, becoming disconnected from the arm 2, will draw the arm 8 upward and outward, turning the rod 0 so that its end 7o hooks will be directed forward in position to instantly shed the traces. The neck-yoke attachment is similar, the rod having guardhooks at its end to keep the pole'straps in position. The rear end of the strap, which is connected to the rod-lever, is attached to a loop on the pole near its forward end, as indicated in the drawings. When the traces become disconnected from the single-trees the forward movement of the horses throws the neck-yoke forward, and the check-strap, pulling on the lever, turns the rod which is pivoted to the neck-yoke so that its end books will be directed forward, and the pole-straps will at once become disconnected, freeing the horses entirely from all connection with the vehicle.

A whiffletree having its central portion provided with a catch and its extremities with rearwardly-inclined bearings, the latter having angular shanks which enter the ferruled 9o ends of the whiffletree, has been used in connection with a rotary detacher having rearwardly-curved ends journaled in holes in the inclined bearings, which latter have traceguards pivoted thereto, and this construction 5 is not claimed herein. A whiffletree has been provided with bent draw-pins in its ends and a rod having quadrants at its ends, which normally engage the draw-pins when the traces are attached thereto, but which, when middle portion by the arm 12 t0 the rod 6, the spring w, and the operating-strap t, permanently secured to the lower end of the leverl and detachahly secured to the upper end thereof, substantially as specified. f

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JNO. H. GLOW.
